Description

Technical Field

[0001] This application relates to the field of fasteners, and in particular to a fastening structure for motor anchor bolts. Background Technology

[0002] Along the coal mine transportation system, equipment such as drive motors, vibratory motors, speed reducers, and crushers are required. These devices are typically secured with anchor bolts to prevent them from moving. To ensure the stability of these anchor bolts, they must be tightened monthly to maintain their secure hold on the equipment.

[0003] Traditionally, anchor bolts are tightened using a wrench. However, since the equipment in coal mining systems is generally large, the corresponding anchor bolts used are also large. Manually tightening the anchor bolts in coal mining systems with a wrench is too strenuous. Therefore, in actual operation, a hammer is often used to strike the wrench.

[0004] The above-mentioned method of tightening anchor bolts by striking them with a wrench is not only inefficient but also laborious. Therefore, it is better to design a tightening structure to maintain the long-term stability of the anchor bolts or to make it easier and less strenuous to restore the anchor bolts to a tightened state. Utility Model Content

[0005] To make it easier and more convenient to keep the anchor bolts in a tight state, this application provides a motor anchor bolt fastening structure.

[0006] The technical solution for a motor anchor bolt fastening structure provided in this application is as follows: An anchor bolt fastening structure for an electric motor includes a fastening drive, a fastening wrench, and an intermediate connecting member. The fastening drive is installed next to the anchor bolt. One end of the fastening wrench engages with the anchor bolt, and the other end of the fastening wrench is connected to the intermediate connecting member. The fastening drive drives the intermediate connecting member to move linearly, and the intermediate connecting member drives the fastening wrench to rotate around the anchor bolt.

[0007] By adopting the above technical solution, a fastening drive component is installed next to the anchor bolt. The fastening drive component can be stabilized in place by the anchor bolt stabilizing device. Then, the fastening drive component applies force to the fastening wrench periodically, which makes it convenient and labor-saving to tighten the anchor bolt. The setting of the intermediate connecting component can better connect the fastening wrench and the fastening drive component, so that the fastening drive component can be driven linearly and converted into the rotational motion of the fastening wrench through the intermediate connecting component. The driving process is easier to realize. At the same time, the fastening drive component can also be automatically started periodically by the electronic control system, thereby periodically tightening the anchor bolt and achieving long-term stable tightening of the anchor bolt.

[0008] Optionally, it also includes a mounting bracket, which fits against the device fixed with anchor bolts. The mounting bracket is provided with a connecting plate, which extends into the device fixed with anchor bolts and has a fixing hole for the anchor bolts to pass through. The mounting bracket is used for mounting the fastening drive component.

[0009] By adopting the above technical solution and setting up a mounting bracket, the installation of the fastening drive component is facilitated. The mounting bracket is fixed to the anchor bolts via a connecting plate. Then, the mounting bracket is placed next to the equipment where the anchor bolts are fastened, thus achieving a stable installation of the mounting bracket. At the same time, the mounting bracket can be removed more easily. The fastening drive component, intermediate connecting component, fastening wrench, and mounting bracket form a complete fastening device. In actual use, only one fastening device needs to be set up. The anchor bolts at various positions can be tightened periodically through the fastening device, achieving quick and labor-saving maintenance of the anchor bolts.

[0010] Optionally, the fastening drive component is slidably mounted on the mounting bracket, and the direction of the sliding of the fastening drive component is consistent with the axial direction of the anchor bolt.

[0011] By adopting the above technical solution, the fastening drive component can move upward, thereby driving the fastening wrench to move upward as well, so that the fastening wrench can be freed from the restriction of the anchor bolt. Then, the fastening drive component drives the fastening wrench to reset, making it convenient to adjust the position of the fastening wrench, thereby better tightening the anchor bolt. In particular, with each anchor bolt having a fastening structure, after long-term use, it is necessary to rotate the fastening wrench in the opposite direction to the original position.

[0012] Optionally, the fastening drive is a jack, and the handle of the fastening drive is detachable.

[0013] By adopting the above technical solution, the fastening drive component uses a jack, which is easy to operate. At the same time, by removing the handle of the fastening drive component, the handle of the fastening drive component will not protrude and affect normal construction when it is not in use.

[0014] Optionally, the mounting bracket has a mounting groove into which the fastening drive component can slide.

[0015] By adopting the above technical solution, by setting a mounting groove on the mounting bracket, the fastening drive component is protected to a certain extent by the mounting bracket. At the same time, the mounting groove restricts and controls the driving direction of the fastening drive component.

[0016] Optionally, the mounting bracket is provided with a groove for the handle of the fastening drive to be fitted.

[0017] By adopting the above technical solution, the handle of the fastening drive can be fixedly placed in the groove after being removed, making it easier to find a wrench for installation when using the fastening drive.

[0018] Optionally, the fastening wrench is located above the mounting bracket, and the mounting bracket supports the fastening wrench.

[0019] By adopting the above technical solution, the tightening wrench is supported by the mounting bracket, reducing the stress at the connection position between the tightening wrench and the intermediate connecting part, making the connection between the tightening wrench and the intermediate connecting part stable, and the connection structure between the intermediate connecting part and the tightening wrench is not easily deformed.

[0020] Optionally, the tightening wrench is used in conjunction with the anchor bolt set.

[0021] By adopting the above technical solution, the fit between the tightening wrench and the anchor bolt is made tighter, and the operation of the tightening wrench is more stable.

[0022] In summary, by installing a fastening drive unit next to the anchor bolt, the fastening drive unit can be stabilized in place by the anchor bolt stabilizing device. Then, the fastening drive unit applies force to the fastening wrench periodically, making it convenient and labor-saving to tighten the anchor bolt. The intermediate connecting part can better connect the fastening wrench and the fastening drive unit, allowing the fastening drive unit to use linear drive, which is converted into the rotational motion of the fastening wrench through the intermediate connecting part. The drive process is easier to implement. At the same time, the fastening drive unit can also be automatically started periodically by the electronic control system, thereby periodically tightening the anchor bolt and achieving long-term stable tightening of the anchor bolt.

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] This application discloses a motor anchor bolt fastening structure.

[0027] Reference Figure 1-3 An anchor bolt fastening structure for an electric motor includes a mounting bracket 1, a fastening drive component 2, a fastening wrench 3, and an intermediate connecting component 4. The fastening drive component 2 is mounted on the mounting bracket 1, and the fastening wrench 3 is connected to the fastening drive component 2 via the intermediate connecting component 4, so that the mounting bracket 1, the fastening drive component 2, the fastening wrench 3, and the intermediate connecting component 4 form a whole as an independent fastening device 10 for fastening the anchor bolt 5.

[0028] In one embodiment, the aforementioned independent fastening device 10 can be provided as a single unit. When the anchor bolts 5 of various equipment in the coal mine are tightened periodically, the fastening device 10 is placed next to the corresponding anchor bolt 5 in sequence for the tightening operation. Alternatively, multiple fastening devices 10 can be provided, with each fastening device 10 corresponding to several anchor bolts 5. The area is divided into regions, and each region is provided with one fastening device 10. When the anchor bolts 5 are maintained and tightened periodically, each region is maintained independently through the corresponding fastening device 10.

[0029] In another embodiment, each anchor bolt 5 may be equipped with a fastening device 10. The fastening device 10 can be operated manually periodically, or all the fastening devices 10 can be connected to the electrical control system for periodic fastening operations.

[0030] In this embodiment, it is preferable to set a fastening device 10 for each anchor bolt 5. At the same time, the fastening drive 2 is a jack, which is easy to operate, has a simple structure, does not require an additional control system, and does not require too much movement of the fastening device 10. Only when the fastening device 10 at the corresponding position is damaged will it be necessary to borrow other fastening devices 10.

[0031] The mounting bracket 1 includes a channel steel body 11 and a connecting plate 12 and a vertical plate 13 installed on the channel steel body 11. The channel steel body 11 has a C-shaped cross-section with the opening facing upwards. The channel steel body 11 forms a mounting groove 14. The vertical plate 13 is welded and fixed to the channel steel body 11 to form an integral whole. The vertical plate 13 is located at one end of the channel steel body 11 and its surface is perpendicular to the bottom of the mounting groove 14. At the same time, the vertical plate 13 closes the opening at one end of the channel steel body 11.

[0032] The end of the fastening drive component 2 away from the piston rod is slidably mounted on the vertical plate 13, so that the fastening drive component 2 can slide along the vertical plate 13 into and out of the mounting groove 14 of the channel steel body 11. The piston rod of the fastening drive component 2 extends and retracts along the length of the mounting groove 14. The sliding fit structure between the fastening drive component 2 and the vertical plate 13 can be achieved by setting mutually cooperating T-shaped sliders 61 and T-shaped grooves 62. The T-shaped sliders 61 are welded and fixed to the fastening drive component 2.

[0033] One end of the intermediate connector 4 is rotatably connected to the piston rod of the fastening drive 2 by bolts, and the other end of the intermediate connector 4 is rotatably connected to one end of the fastening wrench 3 by bolts. The end of the fastening wrench 3 away from the intermediate connector 4 has a hole that mates with the anchor bolt 5. The fastening wrench 3 is installed on the nut of the anchor bolt 5 by means of a set, so that the rotation of the fastening wrench 3 can drive the nut of the anchor bolt 5 to tighten.

[0034] In another embodiment, one end of the intermediate connector 4 is welded and fixed to the piston rod of the fastening drive 2, and the hole of the fastening wrench 3 for bolting the intermediate connector 4 is an oblong hole 31, so that when the intermediate connector moves in a straight line, it can also drive the fastening wrench 3 to rotate around the anchor bolt 5.

[0035] In this embodiment, the intermediate connector 4 moves linearly with the piston rod of the fastening drive 2, which makes it less likely for the intermediate connector 4 to collide with the channel steel body 11 and reduces the requirements for the positional relationship between the intermediate connector 4, the fastening wrench 3 and the channel steel body 11. At the same time, the intermediate connector 4 is composed of two clamping plates 41, which are respectively positioned above and below the fastening wrench 3. The two clamping plates 41 are welded and fixed to the piston rod of the fastening drive 2, which facilitates the setting of bolts to pass through the oblong hole 31 on the fastening wrench 3 and be fixed. The part of the bolt located in the oblong hole 31 is a smooth cylindrical surface.

[0036] The connecting plate 12 is located on one side of the channel steel body 11 away from the vertical plate 13. The connecting plate 12 is welded and fixed to the channel steel body 11 as a whole. The connecting plate 12 extends into the equipment fixed by the anchor bolt 5 and has a fixing hole 121. The fixing hole 121 allows the anchor bolt 5 to pass through. In use, the channel steel body 11 is attached to the side of the equipment fixed by the anchor bolt 5, and the anchor bolt 5 protrudes from the position where it passes through the equipment and has a fixing post 122 inserted into the fixing hole 121, thereby realizing the placement and fixing of the channel steel body 11 next to the anchor bolt 5. At the same time, the direction of the fastening drive 2 sliding on the vertical plate 13 is also consistent with the axial direction of the anchor bolt 5. The fixing hole 121 is larger than the nut of the anchor bolt 5, so that the nut of the anchor bolt 5 will not hinder the disconnection of the connecting plate 12. At the same time, the top of the fixing post 122 is located in the fixing hole 121, so that the fastening wrench 3 does not abut against the fixing post 122 but against the connecting plate 12.

[0037] In this embodiment, the connecting plate 12 extends to one end of the channel steel body 11, and the intermediate connecting piece 4 also extends to the outside of the mounting groove 14. At the same time, the fastening wrench 3 is placed on the connecting plate 12 and is supported by the connecting plate 12.

[0038] The jack used in the fastening drive component 2 can be a hydraulic jack or a threaded jack. The jack includes a detachable handle 21. The part of the fastening drive component 2 with the handle 21 is located on the side of the fastening drive component 2 away from the channel steel body 11. The cylinder of the fastening drive component 2 is provided with a handle 22 on the part of the cylinder where the handle 21 is located away from the vertical plate 13. On the one hand, this prevents the handle 21 from being overhanged and affecting the operation, and on the other hand, the handle 22 makes it easy to operate the fastening drive component 2 to move on the vertical plate 13.

[0039] Since the front and rear dimensions of the jack cylinder may be different, a support block is provided between the main body of the channel steel and the smaller part of the jack. Through the cooperation of the support block, the fastening drive component is supported at both ends. In this embodiment, since the end of the jack near the piston is smaller, the support block is specifically supported at the end of the jack near the piston. The support block can be fixed on the jack or fixed on the main body of the channel steel to keep its position unchanged. Preferably, the support block is welded and fixed on the main body of the channel steel.

[0040] In a further embodiment, the handle 21 is installed on the side of the fastening drive member 2 and extends to the outside of the channel steel body 11, while the handle 22 is still located on the side of the fastening drive member 2 away from the channel steel body 11. The handle 21 is removed when not in use. The vertical plate 13 is vertically provided with a groove 131 for the handle 21 to be embedded or inserted on the plate surface opposite to the fastening drive member 2. The preferred placement method is to insert the handle 21 into the groove 131. The cross-section of the groove 131 is an arc shape, and the opening width of the groove 131 is smaller than the diameter of the handle 21, so that the handle 21 will not disengage from the groove 131 laterally.

[0041] A structural notch 15 is provided on the side of the channel steel body 11 corresponding to the position of the mounting handle 21 of the fastening drive component 2, so as to meet the requirement of inserting the fastening drive component 2 into the channel steel body 11.

[0042] In the aforementioned method of periodic tightening operations via the electrical control system, the tightening drive 2 mainly uses a hydraulic cylinder, which is periodically started and controlled by the hydraulic system. Furthermore, the hydraulic cylinder can be set to a normally open mode, and the output pressure of the hydraulic cylinder can be limited to a fixed value, so that the anchor bolt 5 is always in a stable tightened state. If the anchor bolt 5 becomes loose, the force output by the hydraulic cylinder to the tightening wrench 3 will naturally complete the tightening action again.

[0043] The implementation principle of the motor anchor bolt fastening structure in this application embodiment is as follows: a jack is set next to the anchor bolt 5, and the jack is fixed in position by the mounting bracket 1. Then, the jack applies force to the fastening wrench 3. Finally, the fastening wrench 3 can be fastened directly by the jack without manual intervention. At the same time, the entire structure can be removed and maintained at any time.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
